After the first read I would say it mus have something with your motherboard power connectors (power, restart, hibernate). Try to download the manual of your motherboard and check the headers both at the motherboard and weather the cable lacks isolation and touches the case.
Also you can change setting in Windows to avoid sleep mode : https://www.pcworld.com/article/225833/Tweak_Your_Windows_PCs_Sleep_Mode.html
